Abstract

Polyurethane foam are obtained by using soy- polyols, TDI: MDI (80:20), and surfactant. Soy-polyol is made using a low molecular weight of alcohol; methanol and ethylene glycol. The responses of ethylene glycol and methanol to silicon surfactant has produces a unique polyurethane. With the ability minimized water absorbency. The goals of this study is to determine the optimal conditions of using of methanol and ethylene glycol in soy-polyol synthesis as based substance for polyurethane formula. From this work we found a relation between foam reduction absorption to its morphology and the voids occured, the shape of the surface of the foam, and the curing time of foaming. Optimal conditions of polyol synthesis is found at the ratio of epoxide/methanol is 1: 6 (mol/mol), and epoxide/Ethylene Glycol 1: 3 (mol/mol).
